Cluster analysis with trimming (trimcluster)
Trimmed k-means clustering.

Simulate Large Scale Assessment Data (lsasim)
Provides functions to simulate data from large-scale educational assessments, including background questionnaire data and cognitive item responses that adhere to a multiple-matrix sampled design.

Risk Prediction on Trees (Mangrove)
Methods for performing genetic risk prediction from genotype data. You can use it to perform risk prediction for individuals, or for families with missing data.

Variance-Covariance Matrix for Multivariate Meta-Analysis (metavcov)
Compute variance-covariance matrix for multivariate meta-analysis. Effect sizes include correlation (r), mean difference (MD), standardized mean difference (SMD), log odds ratio (logOR), log risk ratio (logRR), and risk difference (RD).
